If you mean at the live casino, for low stakes (2/5 or lower), you only need one tip: find a starting hand chart from any strategy site, book, platform, whatever. Follow the chart. It will be very tight out of position and loosen up in position. Do not deviate. If you follow it, you will be the tightest player at almost any table.
You should now be a winning player. Most decisions will be easy. Any post-flop improvements will start to mint money.
Other players will note how tight you are and still give you action. They cannot help themselves.
I was a pro player for a number of years, just to give context to this advice. Start with playing very tightly, be instantly profitable, and add skills from there. And please, please, please, don't talk about poker strategy at the poker table.
The other half of this (the "Most decisions will be easy" part) is knowing rough odds.
Four to a flush on the flop? One in three chance of getting it. If a lot of people are in the hand and the flush looks like it would be the best outcome, stay in.
Same with an open-ended straight, and you should know whether others could have a better straight draw than your own.
If you see a bunch of random crap on the flop e.g. no straight draw or flush draw or high cards? If you have high pocket pair or two pairs, get aggressive as everyone else is either drawing (and you want them under the profitability threshold of 3+ other players in the hand) or playing a hopefully lower pocket pair or very ill-guided low two pairs (so watch the big blind or historically loose players).
You can usually calculate in your head how many of the unseen cards need to be somewhere to beat you: Suppose I have the best two pairs on an otherwise unspectacular board. My opponent needs a pocket pair to beat my hand. I have 8 opponents, usually a pocket pair is dealt 6% of the time. Even if I sum all the percentages---mathematically wrong but worse than the truth---it's less than 50% chance SOMEONE has been dealt a pocket pair, so I don't have to feel bad about staying in.
If you can do this quickly and make it look like you are acting impulsively or inexperienced, more money will bet against you.
