2. Learn to do the 'beginning with the end in mind': A lot of us here in India go and buy a plot on a reasonable loan, and then try to clear it off within 2-3 years. This way you get to acquire a resource, make a investment, and are forced to save up every month to clear the loan. This is more like forced savings. Repeat this for a long time, and you will get really really rich.
3. Keep a diary: Keep a habit tracker, try to get a continuous streak of $0 expense days.
4. Pick up a hobby like music: Gets you entertainment without bills for TV/Cable and things like that.
5. Buy for need and durability: Don't buy everything that you see people buying. Buy only if you need something and buy durable stuff.
There are a range of other things I do. But it might get a little too long for a HN post.
