Engage with what has never engaged. Perhaps you've always wanted to try make your own robot or just make a radio out of brahla accumulated at home. And why not? Search the Internet scheme, find out what you need to do and start to create. And when you get something really worthwhile, you will realize that time was spent not only with interest, but also to good use. In the same way, you can collect professional models of ships, cars and reconstruct the entire castles.
Get a tool, which has never been played. Music not only quickly absorbs free time, but also fills the hours spent for classes and rehearsals of its special atmosphere. You already know how to play the guitar? It does not matter. Buy hand-simple synthesizer and continue to play music on it, lunar sonant Beethoven unlikely to be on something to sound the same as the keyboard. But what about the flute? Buy a simple student's flute, and works like "lonely shepherd" stand in a queue in front of you, waiting, and when you get to them.
Buy a new board game. A huge range of different charades, puzzles, and business simulations allow for the whole family, not one night in a friendly and warm atmosphere. Long dreamed of bankrupt husband or wife? Do this at least every night until you are bankrupted children. Do not take too expensive versions of games than outer beauty are virtually indistinguishable, but when the game is tired, the cheapest option is not it a pity to change to a new one, but the other direction.
