I don't know how old you are, but let's assume you're 40.
If don't "go pro", but can find a way to pull out this amount via Swing/Position type trading each year, 20% adds up to a lot, over time. And, this is probably the key, how much you need to "produce" goes down a lot as your supply of money gets higher.
20% (I'm trying to do a basic account for taxes) on 10k is 2k. Not bad, really, as long as the work isn't too much. And, for most people, their hobbies probably cost a lot more than *make* them money. But, roll this forward a couple of years. 20% on 100k is 20k. That's not quite a living, but if you don't have to put in all that much work, that's a pretty dang nice side income.
What if we roll forward a bit further. Say you have 250k in your account. The first note is "NICE JOB!". The second note is that 20% of 250k is 50k. If you're still doing both this & your normal job, you should have 0 debt, a good house, good car and be living real pretty. But this is also an inflection point, as you could (with little to no debt) simply live of that yearly.
So, if you're 40 and this is your "side hobby" until retirement around 65, you will know why compounded interest is so wonderful: $1,192,452. Seems like a nice retirement account, along with other savings you should be doing (401k and the like from work). Pays off a lot better than stamp collecting.
But here's the fun kicker: This is assuming adding no money extract to the account. If you're getting consistent returns, and you have the control to not bomb it out, you can add money.

If you start at $12,500, add 250 a month and "make" 20% per year, you're at $155,272 by year 10. If you can get it up to 40%, it's 100k after 5 years.
But, looking back at the start of the thread... have you taken an account from Jan/Feb 2013 @ $5000 and gotten it to $12500 in 14 months? I think you might be doing better than you realize.
On the "bigger" thoughts, I'm way too new to give technical advice, but I'm very good at self-analysis and eliminating problems. (I have way too much practice at that) If you're consistently *profitable* over *months* and not taking wild swings, that means "you've gotten there". The issue now is "getting over the hump" and getting more out of winning trades/limiting losing trades more. That'll be worth a good bit.
But, the outer goal, is to really refine what it is you "know" happens. What's your Insight. What can you "see" about to happen. What is *your* edge? It'll take a while to both find & understand it. Don't fret if you don't have it for a while. Most people never got to that point in whatever it is they do. But let the concept rumble around in your head. What do you consistently "hit" in trading? Like Smart Money, it leaves hints.
If you find it, refining it and cross-applying it is where the "big money" shows up. Whether in Trading or Academics. Not joking. This is an adapted version of an insight one of my professors gave me about being "great" in the Sciences. You find your 1 key Insight and just apply it everywhere you can find to apply it. It'll make an entire academic career.
Keep it up, you're already doing really well. And a whole lot better than most traders. Be glad in that and relax. Step into the next phase in confidence.
