Laboi_22, I'm afraid I disagree with Cathy and Novella because it is bloody difficult to get a goddamn agent or a traditional publisher. It took me a few self-published books and a short story award to get a proper publisher and now an agent - after a properly published novel. This said, it is probably easier to get a publisher than it is to get an agent to look at your manuscript. Check every agent's submission requirements and you'll understand what I mean. I have a rule of not saving rejections because I prefer to be positive. But If I did, keep them, before I got to where I am now, rejection slips alone would make a novel and a sequel, maybe even a prequel.
In a typical catch22 scenario, it is relatively easier for a publisher to consider your work if it is coming from an agent; it is easier for an agent to consider your work if you have been traditionally published or have won an award from your writing or have received a traditional offer of publication and would like the agent to negotiate the terms of agreement. But if you are a member of a society of authors who provide contract review as part of the services, then the agent is superfluous unless, of course, you wish them for further works.
All I can advise is for you to get your manuscript in the best possible form ever; get someone to read it, preferrably an approved appraiser/ critique group (as Cathy has mentioned) who will not only review your bloopers but your structure and plot (!!!). You may have to pay for this service and it is worthy of it. Ever heard anyone say their kid is ugly - even if they have close set squints and chipmunk masticators? Exactly. You may love your work, but it is not necessarily perfect. Only and only after a third objective party has commented upon your writing, and you have revised it according to your judgement, should you send it to an agent or a publisher. The rest is name, market research, family ties, contacts - even before the quality of your writing - deity and good luck!
Just don't give up.
