Infinity Gauntlet in 5 easy steps:
1. Be born a super strong Titan whose home planet was destroyed due to over population
2. Spend the rest of your life trying to find balance by killing half of the universe
3. Once Shield is gone, the Avengers are split apart, Odin is dead, and Ragnarok has destroyed Asgard, invade Nidavellir and force Eitri to forge you the infinity gauntlet.
4. Collect all the infinity stones from across the universe, I recommend finding the Tesseract/Space stone early on to save on travel expenses and time (the Eternals wont like what you're doing, so you have to be quick). Once you also have the Time and Reality stones, it should all be really easy.
5. Snap your fingers, balance restored.
Or ask Sub really nicely, but I think you will have better luck with the above list.
