How do I get rid laziness of learning new things?

The answer depends on who you are.

If you like reading, then read a lot. Through reading you'll get interest in new things and you will enjoy learning those new things.

If you hate reading, your first step to improve yourself is to like reading by following these steps:

Read as little as you can everyday (start small).
Read only things you like.
Read anything you like even things you think are silly or waste of time.
Keep reading... forever.
Watch movies that are related to what you want to learn, this might give you some motivation.

Make friends with people who already work in the field you want learn something about.
