There's nothing to say you can't enjoy life. Buddhism teaches mindfulness, which encourages you to appreciate where you are. There is joy to find in simply appreciating your circumstances, rather than striving for things like material wealth endlessly. It teaches escaping the treadmill of accumulation which ends up controlling us. By grasping interconnectedness, possession is left behind, and we liberate ourselves from suffering.

Thats my understanding, anyhow. Ive got a long way to go still.
