Never stop dating your partner. Time will pass you'll get complacent and fall into a routine. It happens and that's fine but Be aware of it and break the cycle, buy them a random gift, take them somewhere nice where you both get dressed up, leave them little notes around the house, do something they've been asking you to do but you keep forgetting or putting off. A relationship is work, so put the work in.
Any time you make any amount of money, put 5% of it into a savings account. If you don't have a savings account, make one. If you can't make one, put the money somewhere safe in your house.
5% doesn't sound like a lot, and for broke/poor people it can often mean the difference between eating that day or not, but if you're able to do it, really seriously do it. I recently calculated where I'd be right now if I had done that, and I would have saved over $20,000 in the last 15 years if I had listened to my own stupid advice.
Also, wear moisturizing sunscreen every single day.
Proper dental hygiene is something that one should make a habit from a young age. By the time one realizes its value, like I did, it might already be too late.
Ditto with sleep hygiene. Those two are habits that I think should be learned and reinforced from a young age.
Treat your body good. Eat well and get some kind of exercise into your daily routine. Even Walking 20-30 minutes a day is enough to keep you healthy enough.
When you get into your mid 30's things get harder.
Don't argue with people who are obviously trolling, obviously acting in bad faith, or obviously don't believe the shit they say. Their plan is to get you upset and make you slip up, or keep spouting BS as you give them an air of reasonability.
Block them. Make it a habit. "Oh obvious troll" -> blocked. This is the best thing you can do to clean up your social media experience.
The other replies tell you the simplest method, however if you decide you like Liftoff and want automatic update support, I would recommend Obtainium. To add the app to Obtainium:
Go to the Github Releases page for the app and put the url into "add app" in Obtainium.
Stop caring about the intentions of other people. Focus instead on the effect that they have on your life.
In special: get away ASAP from people who are eager to point fingers at the others, with little to no reason, and even when proved wrong will still double it down. Don't allow them in your social circles. Your future self will thank you.
