What a lot of people mean by “live in the present” is have fun today and don’t worry about the consequences. That’s not what I’m advocating.
Instead, I want to address looking for happiness in the future. Sadly, I think we tend to put off happiness. “I’ll be happy once I have a bigger house/move to another town/lose ten pounds/etc.”
Circumstances can make a big difference. I feel a huge wave of relief when finals are over. But at some point, if we can’t learn to be happy now, we’ll always be looking for the next thing that promises happiness.
That’s why I’m working harder to appreciate every moment as it comes.
