It's a simple quote, but not very useful.

The past isn't generally depressing and there are lots of things worth to be remembered. The past is not only in my mind, it is around me all the time and it is the context I'm living in.

The future needs some planning.

We just need to live in the present, but also have to make decisions based on past&present&future.

Shuzo Matsuoka rephrased this in one of his motivational speeches, and just like that it sounds less absolute:

"'I want to feel alive!' Its easy. You cant think about the past. 'Why did I do that??' It'll just turn to anger. You also can't think about the future. 'Will it be okay?' It just turns to worry. In that case, hold on for dear life! Stake your entire life in here and now!"
