Never quit or give up on alternative sources of income, try to manage them along with the BTC trading. Because anything can happen in BTC, it can make you lose all if you are into future or margin trading but if you are in spot and trading wisely you can make some decent money but in order to make decent money in BTC via spot requires more funds and if you lack them you will definitely going to do future or margin but that's highly risky for a newbie even for an expert because both lose money in this market.

The advise of not investing your life savings into BTC trading is good but I would like to add that you must not do BTC trading but you must do BTC holding with your life savings. As your life savings are for either retirement or for some emergency funds. Most people keep emergency and savings funds aside I prefer them aside. Keeping your savings in the form of BTC is a better way to make money on it without the APY or other bad stuff. My savings are in BTC and I am making more than 2x on them right now.
