Just make sure that you differentiate between wishes and goals. Goals are within your reach; wishes have more to do with luck. Compare it to playing the lottery. You can buy a ticket or tickets religiously and tell God or your teddy bear or whomever just how much you want and need that money, but in the end it's dumb luck whether your numbers are picked. In other words, you can't set a goal to win the lottery. You can only play and wish.
Now that you've written down specific goals, it's time to pick one. Which is most important to you? That's the one you need to focus on. Keep your list with the other goals on it -- you can go back to it after you accomplish your first goal.
I know, you want to multi-task, but you're far more likely to meet a goal if you're focusing on it, rather than juggling several.
Instead, start with a specific mini-goal you know you can achieve. For example, "I will write for 15 minutes at least twice a week over my morning coffee." Caveat: start smaller than you think you need to. If you set the goal too high -- say, 15 minutes every day -- you're likely to fail and get the goal-violation effect, and then it's all over.
4. Be realistic -- and use common sense!
If you want to get an agent, write out all the steps not only of getting the agent, but also of preparing your manuscript and query. Too many people rush out to find an agent before their work is really ready. Build in plenty of mini-goals in which you get lots of feedback from other writers -- and listen to what they have to say. Then you can consider sending your material out.
5. Take it slow.
Once you accomplish a mini-goal, take some time to make it a habit rather than rushing on to the next mini-goal. If you're able to write for 15 minutes at least twice a week over coffee but you feel like you just barely pulled it off, the very last thing you should do is move up to your next mini-goal of writing for 15 minutes at least four times a week. Instead, take some time making writing over your coffee a habit. Only once the task is regularly coming easily -- perhaps you even find yourself looking forward to the two days -- should you move on to your next mini-goal.
Likewise, give yourself at least six months to a year to find an agent. Longer -- think two to five years -- if you have yet to have your work critiqued by objective strangers, if you need to build a platform, or if you need to get some short stories published to establish yourself.
I know you're impatient, but remember, it's better to get there a little slowly than not to get there at all!
6. Reassess at least once a week and make changes as necessary.
If you get to the end of week 2 and you're really struggling with your mini-goal -- say, you just weren't able to get yourself to write for 15 minutes twice a week -- don't beat yourself up. Just troubleshoot and adapt. Make the mini-goal 5 minutes twice a week. Then work your way up to 15 minutes.
If you stick to the tips above, though, I bet you'll find that your goals are much more manageable and achievable than they were before!
