Life is going in circles - resetting it very self.

Set yourself smaller, more achieveable goals. Saying "I want to be a top programmer" is a hell of a goal to reach and failing to do so will make you more depressed. Saying that you want to learn to do a bit of programming in a specific language is far more achieveable and once you manage that you'll feel better about yourself.

Even if you've completely given up on the programming, try to think of something you would like to achieve and focus on that. Even if it's something dead simple, once you manage to so that you'll start to feel better about yourself almost immediately.

People rarely achieve everything they set out to in life so it's important to remain flexible and reassess where you want to be going from time to time. The worst thing to do is compare yourself to your perceptions of other people as you never really know what their lives are like. All the cool people you see are probably hollow and empty inside and tired out from spending all their lives concentrating on their image and not happy at all.

Small steps is always the way forward.

Jam it back in, in the dark.
