Timing my proposals

[89640a22]

I am relatively new to Upwork, and I would love some input about timing multiple proposals. For those of you who have been doing this for a while, do you:

1) Submit a proposal for every interesting job, knowing that if they all hit at once you will have to scramble to get them done?

2) Figure out a percentage of positive responses and base multiple proposals on that?

3) Discipline yourself to submit only a certain number at a time and wait for a resolution to those before submitting any other proposals?

There are so many interesting projects that pop up, so I would love to hear how others handle this. I am in the editing/proofreading field. Thank you!
