If you can read, then you can cook. The hardest part about cooking is actually not fukking yourself up with burns. As long as you use the general safety guidelines and good equipment, you should be ok. Start slow with breakfast food, then work your way up.
As for culinary thermometers...I never used those.. I trained my eyes, for example, what a medium well steak should look like and when it's needs to come off the grill or stove. I can do well done(without burning), medium, medium rare and rare as well. Once you've been cooking for a while, you'll get a feel for how long something takes.
Invest in pots and skillets (especially) with lids... Anything that cooks covered, cooks faster.
Buy oven mitts, unless you wanna use your dish or drying off towels(lol.)
Medium heat works for just about everything. It doesn't cook too slow or too fast; almost nothing boils over(milk will though) or scorches.
Hit me up if you need anymore advice. I have more than 10 years work experience with restaurants and have been cooking since my teens.
