Wasting Time

Could you define constructive? Is only school, work, etc count, or anything with a product? Like, let's say, using Photoshop. I enjoy it, and I make something, usually something that I wanted to make, not on someones elses demand. ... But I never do that, I usually just use it for entertainment.

There are times when I simple do not like to do interesting and useful things on the computer and plays the whole day so I believe it is simply like this where we feel a bit lazy to do some constructive things on the computer and instead take it easy and waste a bit of time.

I like computer.It is a wonderful thing.I spend much time on it every day.You can use it for entertainment,such as computer games,watching videos.And you can also do some constructive things,for example,I usually develop games on it.

I use my computer mainly for earning. I spend very less time on entertainment.
