Ideas for frugal/cheapo FIRE lifestyle

There are many categories of people, this particular post is for the MMM category of frugal people who had a very grounded lifestyle inspite of high earnings and maintained a savings rate of 50% of more.

So basic day to day essentials there is no compromise, we need to spend on groceries, utilities, rent etc.

This post is mainly to do with how to spend time; without spending money on expensive hobbies.

Here are some of my ideas:

1) Do a lot of train journey all over India; mostly solo trips, because wife and kids are unlikely to enjoy it and kids go to school and wife will be busy with their own life. FIRE is mostly a personal journey. So I am thinking of starting with week long solo trips initially and see how it goes. I am based out of Bangalore. So a train straight to Delhi/Kolkata and then explore the mountains slowly either in Himachal/Utarakhand or in Sikkim/West Bengal.

2) Motorcyle solo rides mostly south of India.

3) Buying used motorcyles for cheap good deals and then fixing them up and selling them for a profit.

4) Doing NISM course in financial markets and somehow getting into the advisory/mutual fund eco system. Although I am not sure how to start. I count this as a hobby, even though it is work for the people who do it. The reason I count it as a hobby is because I am interest in financial markets.

Those are the ideas I could come up with based on my interests.

Cheers!
