1- It's ok to think of your problems as long as you're going to do something about it, and it's ok to criticize yourself as long as you're going to change what you don't like about yourself! otherwise, you're breaking your own heart.
2- It may feel sometimes like your life is crashing down and like you're facing a hard time that you may not see an end for it, but this is not true, you've been here before, you had faced such moments before!! and in the end it's all about attitude, how you see those hard moments, so change your attitude! see it as an opportunity to learn and to grow up! take the good from every situation you're going through, don't let a mistake pass by without learning the lesson.
3- We're human beings, it's normal to feel afraid, there's no shame with feeling so, but the shame is to make it as an excuse to not take actions on your dream! so be afraid, but do it anyway.
4- The only thing you have control over is yourself, your words, your actions and even the way you choose how to feel! what others will do isn't something you have control over so give up expecting things from people! you can never expect anything from anyone! and when you do just remember that this world doesn't owe you anything!
So before blaming others, why not to have a look at yourself, before judging make sure that you're perfect!
5- Always show all the love and care to your loved ones, show kindness to the rest and for the both of them always be respectful, respect your difference, and respect it enough to never judge anyone, keep the rudeness to yourself this world is already full of it.
6- When you give out your best, you'll have what's even better to give! Don't be afraid to let go of who you are for the one you want to become, because you only get better when you let go of your old self! you only can do it better when you bring out your best every time.
