Working fulltime as a software engineer/developer/sysadmin, I start to get tired of the job.

The income is limited in a sense that same amount per year. People have limited time. Working on pay-per-hour is the worst way to generate income. So business and investment is a must.

Realising this in the early days, I learned Forex while was still studying at uni. So now I'm trading forex part time, making some saving from the full time job then at some point I'll switch over to trading forex full time.
