The question I ask for everything that you're going to achieve within your life. You wana graduate..then? Buy a house.. then? Be a good parent..then? Make more money..then? Become the best in your career..then? Save the world..then?
I've been thinking lately that goals don't make us leave the bed in the morning. No matter how noble your goals and visions are they're not the reason you're fullfilled.
The thing that matters the most is how much Impact we can make on others on a daily basis. The idea of helping others and giving without expectations is the real push in our lives.
The answer is: there is no "then", just do more good.
