Our first Yama is Ahimsa/Nonharming.
A great start to living your yoga is ahimsa. Living a life of nonviolence means you resist participation in physical and verbal abuse of others, or yourself.
Holding yourself to an unrealistic standard and striving for perfection are forms of self abuse.
Try a little and choose compassion today. First for yourself and then for others.
Take it further by pledging to make all things better than you found them. That can be done by paying someone a complement, picking something up off the floor of the store your shopping in, or practicing a random act of kindness.
* when you feel something negative come up: a negative thought about yourself or others or just plain complaining, replace that thought with a positive one (in your head or maybe out loud). And then treat yourself with kindness instead of beating yourself up for being negative.
