Be ware of the destination trap. Beware of Arrivism. Life is a marathon and not a sprint.
You have probably left home at some point, maybe to do shopping or even schooling. Sometimes, you ran to these places, other times you walked, or were conveyed by some form of transportation. In whichever form, you arrived at the destination and returned home. Embrace this part of your story. There is no place like home.
Do not burn your bridges as you leave home. You are part of an ecosystem that is your family. In your family, you built your first and most intimate relationships. No one knows you like these people do, at least not as yet. Your friends? No, because you would go to them and return home. Home has been your true North. Of course, in all the excitement, you may roll your eyes at this!
The True North is the point on a compass to which the needles always return. It is like they move away, just to do a short gig and quickly return to their comfort zone. There is a comfort you are leaving and shall need to recreate. It has taken years for you to become a young adult. Do not assume you shall recreate your comfort in days or months.

Marathons are endurance races. It is more mental than physical. You can not look back and see what you have covered, and you can not look forward to the end. You simply follow the markers, look for water stops, and run. Meanwhile, your muscles are telling you to give up. You have to think about regulating your breathing. Your feet are tired of wearing shoes. Everything is yelling, ‘Give up!’ Yet you must keep running.
One, brace yourself for negative emotions. You shall feel lonely. You shall be disappointed, discouraged, and distressed. You shall cry a lot, especially for your mummy. Yes, and it is okay. Embrace the tension between growing into an adult and remaining a child. This is the point where many become addicted to substances to numb the pain. Pain is only an indicator that you are not handling a situation well. It is absolutely normal. Do not numb it. Deal with the cause of the pain.
Secondly, have at least three friends whom you can call at short notice. Life throws curve balls at you, and you need a team that will help you hit them back. Solomon writes that a friend loves at all times. (Proverbs 17:17). Of course, there are backstabbing friends, even Jesus had Judas, and Jesus was the son of God. What about you?(I addressed this is One.)
Thirdly, siblings are gold. If you do not have any, you will have friends who are like siblings to you. These are valuable. Solomon says brothers are born for adversity. (Proverbs 17:17) In His book, The 7 Habits of Highly Effective People, Steve Covey introduces us to the notion of an Emotional Bank account. When we treat people the way they want to be treated, we make deposits into their emotional bank accounts. We make withdrawals when we need them to do the same for us. The key word here is need. You shall need to withdraw from your siblings’ bank accounts. Do not ignore them, respond to their texts, better yet create family groups on social media. Have regular hangouts at home and outside home. Spend time together. Invite them over for sleepovers to your home. When they need a place to chill, let it be your home. Take it from Solomon, the wisest king, brothers will pull you out in adversity.
Lastly, find a Church. As you were oscillating to your True North, the faith you carried was not your own. It belonged to your home. You need to believe for yourself. John tells us that the victory that overcomes the world is our faith. (1 John 5:4) He also reminds us that Jesus did say that we would have trouble in this world, but we were to be of good cheer because He had overcome the world. (John 16:33) Ultimately, Jesus Christ is the best gift you shall ever receive in your life because He is eternal life. He brings His peace and joy that never run out.
These things I have spoken to you, that in Me you may have peace. In the world, you will have tribulation; but be of good cheer, I have overcome the world.”
John 16:33 NKJV
