There is no point. At least, there's no overarching design or plan behind your existence. Instinctively we are driven to survive, so the question is: what else?

While we exist, we have senses which can provide pleasure or pain, so the most selfish answer would be to seek pleasures and enjoy them while you can. The correlary being to minimize pain or suffering, which serves as a check on unrestrained pleasure.

I like to take this a step further and work not only to optimize my own pleasure, but the pleasure of others around me. Then guilt is no longer an issue because your pleasure is complementary to theirs. They benefit when you reduce their pain and vice versa.

I believe the original problem stems from artifically self-imposed limitations and expectations on what should be, rather than engaging with what is and imagining what could be.
