Curious:

This may be a COMPLETLEY newbie question, but here goes:
I'm currently a level 34 Summoner. I've been thinking of maybe taking up a serious crafting job to make some extra gil as well as craft my own gear and meld my own Materia. So being a Summoner I'm thinking going Weaver. Now my question is do I even need to be worrying about this? Some players have suggested I simply focus on leveling my SMN and not bothering with crafting until after I cap for the first time. I myself I'm really wanting to do some crafting on the side as I get through my levels, but don't want end up really hindering myself in the process.

What is the general consensus on this? Is it ok to take up Weaving to start making my own armor and selling the extra to make some gil, or; is it better for me to stick to leveling and then work on crafting later?
