Everyone says it's never too old to learn, and we should have the concept of lifelong learning. The purpose of studying now is to increase knowledge and make progress every day. In order to live a full and meaningful life every day.

Study hard now for the present, not for the future. What we can do today also tells us that we should live every day now instead of thinking about tomorrow forever.

Thinking too much about tomorrow and the future will disturb the mind of studying now and distract our attention, which is not conducive to our study. That will become an illusion, not an actual action.
