most worthy skill

I'd say fishing. On the way to 99 I caught enough lobsters to get 25m, and it was relatively fast exp. Sharks are also about 100k an hour, much better than mining or wc when I work on them.

woodcutting ftw!!!!!!!!! wish i could get it to 99 though

this one is easy :) it has to be farming, you can be making around 300k per day from just 10 minutes of work per trip. even with a low farming level 38 ish you can plant toadflax, the seeds are about 639gp and the herbs sell for 2078gp. i average around 7 herbs per seed which when i sell goes for around 15k. i always plant 4 patches and i end up with 60k from just 10 minutes of work. not bad profit if you think about it.

The word worthy, means how you feel it can make an impact on your life and others around you. So, knowing this I would have to say Woodcutting. Not because of the profit, because in reality unless you have 99 woodcutting there isn't much of a profit, but woodcutting is a resource used all over the world. I mean it is used to fletch, to firemake, to just get experience in itself, and it also helps for like the boat rides and everything else you can imagine. As for money making purpose I would have to say farming or fishing. Both give really good payouts.

I would say Woodcutting is the best moneymaking skill, i am lvl 74 and i cut yews in rimmington for 18 hrs, and the get lots of gp, depends on the price, get about 50-70 yews per hr.

i think it is mining because if you get say to level 85 then it is .5 mill an or more hour and mining is my favorite thing to do because miners talk a lot like me and not a lot of spamming like when you are cutting willows in draynor village.

Well I find all of them worth of training. Now for profit that's another manner entirely. I'd have to say Woodcutting & fletching then. High alching bows is good profit.
