This is a discussion on Need betting advice within the online poker forums, in the Learning Poker section; I'm new to poker, only been playing a few months and only play online. I try to play "tight aggressive" but I have an issue
Playing tight aggressive is not bad overall by any means but don't think of it as something you should strive for but think of it as an end result to playing well. I mean that you should still be playing your opponents and not your cards all the time. If you are at a table that you think is folding to you too much then you can open lighter. Reverse is true if you are at a loose table and you don't want to throw chips around with them. It is better to play exploitatively then to have a mindset where you only want to play the top 15% or so of hands. Be observant of the table you are on and if you feel they are folding too much then bet more. If you feel they call too much then bet less and have stronger hands when you do bet. I think this will alleviate what you are talking about.
Getting no action is a fine outcome, unless you have a really premium hand like QQ-AA. This is especially the case in tournaments, where stealing the blinds and antes become really important, as blinds go up.
