A second job can work, but it really depends on what you're actually dealing with. The math matters here - if you genuinely need an extra couple hundred a month to breathe, picking up some evening or weekend work might solve it. But if you're already exhausted or your main job is demanding, adding more hours just spreads you thinner. I've seen people make it work when they find something flexible they can actually stick with, versus burning out after a few months because they're working nonstop.
Before jumping into a second gig, it's worth looking at the bigger picture first. Can you trim expenses anywhere - renegotiate bills, move to cheaper housing eventually, cut subscriptions? Sometimes a small gig helps, sometimes it's just a band-aid on a larger problem like being underpaid in your main role. If your salary genuinely hasn't budged since 2023 while everything else costs more, that's the real issue worth addressing - whether that's asking for a raise, switching jobs entirely, or yeah, supplementing with extra work if that's the only option right now.
The realistic answer is it can work short-term, but don't think of it as a permanent fix. You need sleep, downtime, and a life outside work. If a second job gets you through a rough patch while you figure out a better move - like landing a better paying position - that makes sense. Just don't let it become your forever situation where you're grinding away and still barely making it.
