How much should you tip for a haircut?

Hello my fellow wikiHowians! Long story short, I’ve got a tattoo I want to get rid of. I’d like to completely remove it if possible, but I’m also down to just cover it up if I can’t remove it. I really can’t afford laser removal right now though, and it’ll be a while before I can cover it up with another tattoo if that’s what needs to happen. I’m curious if there are any DIY tattoo removal methods I could pursue? Are there like…creams or natural solutions that will get rid of the tattoo? Can I replicate laser removal at home? I’d even be down to try just lightening it a bit if I can’t get it fully off.

Ugh ugh ugh, I just moved into an older building recently and noticed a lot of those gross silverfish bugs crawling all over the place. Like, I know they're not going to hurt me or do anything, but I'm still getting an icky feeling knowing that they're in my home. I just want them gone as fast as possible so I don't have to deal with them anymore. Any tips to make my place silverfish-free for good?

When I look in the mirror, I just feel kinda blah about how I look recently. For the past few years, I've dressed the same, done my makeup the same, everything the same. I feel stuck in a rut and just want a totally different style that makes me look my best. I've never really done a makeover before, so what are the basic steps I should follow? FYI I don't really have a lot of extra money to buy new makeup or supplies, so any budget-friendly options are a huge plus.

Haircuts have gotten so expensive and I really don't feel like paying for one when all I need is a basic trim. I'm pretty confident I could cut my hair on my own, but I'm a little afraid I'm going to screw it up. Any tips for trimming hair at home and making it look good?

How do I refocus and find a new purpose in my life after I lost my purpose?

Look, I know I’m not the coolest dude of all time. I think I’m funny, I’m pretty nice, and I’m not particularly bad looking, but I know I’m not cool you know? How do authentically cool people manage to come off so laid back and un-cringey. How do I do it? How do I get that cool kid energy? I’m a boy in high school if it helps.
