NObody told you you shouldnt be playing 42s. Not if you are starting playing the game (you said you dont have many hands). I think that is the best I can tell you.
The suited connectors and one gappers require a very good both preflop but specially post flop play. In My case, if I have anything less than the nut flush draw and I want to stay, I try to limit the field, because most of the times when you are in a multiway pot and there is a flush draw, and you have two or more callers it is very likely that someone is drawing a higher flush so you are drawing deadt.
Yesterday I played a hand with suited connectors, and i hit the runner runner flush. I had position over one player and since I checked the turn he bet full size pot on the river, when the flush hit. He was a very aggressive player, and I didnt buy it. I pushed with my nine high flush and he folded.
In that case I had mid pair a flush draw and was heads up. That is all you can ask when playing the suited connectors or one gappers. He called my continuation bet and the turn gave me my flush draw. Since i was in the button my strong flop bet got me a free river. When I hit, I was playing for my stack, because that is why you play the SCs and it was very unlikely that he called my 3/4pot bet on the flop with a runner runner flush. I wasnt going to chicken out.
I just think you have many other ways of improving in the next few thousand hands. Leave the suited connectors for later when you feel you are one of the dominants players at the table and when you dont have that yellow phone over your head in the table

(I am kidding here...but most of us started as calling stations, I am included there).
Also, in the lower stakes, I find so many tables where I just dont want to play them, because flop folding equity is just almost nonexistant. Yesterday I was playing at two tables that had WtSD over 40%. No way I am putting pressure with SCs there.
Play your good hands and when you are able to let go and overpair, AA,KK two pair in a flushed and 4 to str8 board, then I think you are ready to start playing the SCs, following a very aggressive strategy with them.
