Need help learning to stand up!!

[zero_chances]

Ill start off by saying my feet are kinda big, i have size 14 fox boots. I moved the shifter up a little to make shifting easier while sitting. But while standing, i either rock my foot back on the peg to up shift, or grip the bike with my legs and kind of lift my leg up to shift. Thats the way I usually do it, but im not a professional or anywhere near
