One of the most important thing i came across in my life is to achieve what i need,no matter who you're be selfish to achieve what you need and deny what's not needed!
In my point of view : You must take 3 steps/ strategies to achieve in your life
1) Plan your goal
2)Focus on what's good for you
3)Work hard for it
One of the best motivation
Focus on your goals,no matter what distracts you!
Keep on Moving! :)
