Most of the achievement in life comes from the time you suffered in short term to enjoy the long term benefits.
Nothing good comes easily and suffering never last. When you are about to start something new it looks harder, but when you are in already it becomes easier for you, just know the suffering is for the short terms and the gains is in long term.
Don't be afraid to start something, no matter how hard it is for the short term, when you start seeing the results añd benefits you would ever remember you suffered to get there.
