You can guess at the future but you can never be able to predict the future with precision. We can barely frame the present state in its exactness much less do so in the future where all the variables aren't accounted for.
We can only hope that what we do today will somehow benefit tomorrow. But you won't know how goodness shows itself tomorrow until we produce goodness today. It's very much like playing the lottery -- you have to buy the ticket before you have a chance of winning -- except the odds of making things happen in life are much more favorable.
Do good today and don't be surprised something good happens later. And if you keep on doing good, your odds will only get better. Work hard and do so consistently, and pretty soon, the odds are so much in your favor that you will be tripping over good fortune.
So invest in yourself. Invest in your future today.
