My son, as you're going to school, you need to study hard, you need to be the best. In order not to find yourself in unhappy circumstances, you just have to put in your best. Know when to read your book, know when to socialise, know the kind of friends you follow, so that they don't distract you from the main goal.
Your main goal is to study hard and also to connect with friends that can lead you to your purpose and what you're created for. Be wise, be vigilant, be brave, be discerning and be confident. Don't allow anybody to shake your self-esteem.
You can still do it, you can still be the best.
And never stop trying until you reach your goal. I wish you good luck in your endeavour. Go and make me proud, my son.
