To be successful in life, we have to divide our goals in three ways.
Short term goals
Mid term goals
Long term goals
First of all, work on short term goals, when they are completed, then we can move towards mid term goals, by then we are definitely ready to achieve long term goals. The experience of achieving short term and mid term goals makes it very easy for us to achieve long term goals. All this is a one time investment of life, the fruits of which we keep getting throughout life.
