I have shaky hands because I take asthma medicine and I have never really learned what I'm doing. Please help.

I am white, fair-skinned, brown-eyed,and brunette, btw, and I wear makeup every day - usually tinted moisturizer, mascara, powder blush and lip-gloss, no no fancy cat-eye needed. I just want a basic routine. There are a bunch of black liners in my makeup collection and one brown liquid liner.
