Life is a race and some people will move faster than the others but one thing is certain, we are all going to get to our destination no matter how slow we go...
Don't get depressed when you see others happy and don't let other people achievement discourage you ,don't look after anyone's success instead focus and pursue your goal.
Time is too short to waste yours in trying to impress others, don't envy your friends due to the expensive things they put on as you don't know the source of their wealth and don't try to be like them, our path to success is different....
Looking back at others achievement brings you back from achieving your goals,it wont make you to go forward .when you don't look at them and you keep struggling,when you get to d top and then look back to them ,you will see you are above them.
Time is gold,and everyone has its own time that ticks,don't imitate other's people dream just because you are friends .
Someone's achievement doesn't mean you are failing,its just not yet your time,so keep struggling.
Helping others also take you to the top don't try bringing someone down because they are successful than you,instead be happy for them and focus on yours.
