You should learn as much information as you can about the vegan worldview. If you understand their ideas, you'll find it easier. This https://inspirationalsouls.com/being-vegan-vegan-being-samantha-shorkey/ is an interesting blog by an Ottawa vegan athlete. He gives his thoughts on veganism here. I got a lot of motivation after reading it.

First of all, you must start slowly. Don't go to extremes because your mind will sabotage and you will want even more animal food. For starters, give up one thing, such as pure meat, then give up eggs, and then dairy products. Eat enough calories, otherwise hunger will cause breakdowns. Be sure to include legumes, they will subdue the urge to eat meat.
But you can watch the movie Earthlings, then it will be faster lol
