I only read for myself. Oh and sometimes for my partner, and strangely it works (both the reading and the partner part LOL).
I read for self-reflection, I think. I use tarot -when facing issues/questions- as a tool to make me see things in a more intuitive way than I do normally. Thus the concentration part before reading (actually even before shuffling) is very important. I turn inwards completely, visualize the 4 elements, I have my own little sentence to the Creator for asking help and guidance.
Only short 3-5 card readings.
I also do daily cards but it depends when I have time or feel the right moment to do it, sometimes in the evening (to "meditate" on the card during the night and let it influence my dreams) sometimes in the morning (to know what will be the theme/energy of the day). I used to do a 3 card reading in the morning based on the Body Mind Spirit spread, something like (apologize in advance for lousy translation from my mother language):
1- What does my body is telling me today
2- What do I need to focus on today
3- What do I receive and/or give forward today
Really for me tarot is mostly counseling, I started to get into tarot when I was and felt very isolated from my family, I missed at the same time an ear to listen to my problems, a shoulder to lean and cry on and some pads on the back, smiles and good advice, I think. Yep, you could say that tarot is a friend, the kind of incredibly friend that makes you trust yourself more
