What worked for me was getting allergies under control with medication. I used too have red eyes at least 3 times a week and full time irritated. Because of that, my eyes were always a bit swollen and thus my prescription was different than it should
Investing is something you do for the long run. Investing today and getting it all out in a month will probably make you lose money. The market will always go up and down but zooming out, it will go up. Investing in the long run will make you money. Investing in the short run, will make you vulnerable for market ups and downs.
So my tip is, invest a monthly a fixed amount of money every month (dollar-cost average) and don’t touch it for the next 5 years. Yes, also keep your hands off it when the market is going down.
