There are no way to find a side jobs that you wont sacrificing any , like your time , sleep or energy because my self right now even i do work remotely as well as sidehustle i still don't have time to play on my child and also lack of sleep which you really need to sacrifice those things for you to achieve those things. Lucky those people who can still manage their time but again don't go over it that your health will got affected.
Unfortunately, many people are now paid insufficient wages for a normal life at their main job (employers, taking advantage of the crisis, reduce wages, threatening to fire them). In addition, inflation leads to higher prices. That is why moonlighting becomes a necessity.
It depends on the nature of primary job that you have. For the people here in a third world country, most of us here works for a minimum of 8 hrs 6 days a week, making it almost no time to perform a side hustle after your shift from your primary work ends for the day. I knew some people have the will to do 2 jobs every day, but I didn't see any significant changes in their financial status. Low paying jobs and continued high inflations are actually depriving people from the lower category to have their time for their family and for themselves, because working 8 hrs a day may not always going to be enough to feed his family.
Finding a 2nd job may not be necessary if you knew how to upskill and equip yourself from all the jobs that is in-demand over the internet today.
