Is it sensible to quit full time job for Forex?

I always believe we should be sensible with how we approach things and don’t take emotional decisions, as it’s something that could really affect us badly. I am doing a full time job and as part time, I work in Forex yet I make near equal to what I get in my full time job. I believe in future, I might quit my job, as I am able to make great income here especially thanks to OctaFX broker with their low spreads from 0.1 pips for all major pairs while there is also 50% bonus on deposit which is use able!
