Yes it is, I'm pretty sure one I did is about to fully materialize. It as a job spell I did middle or end of winter. I thought about what would be ideal for a while, then I simply wrote a 5 item list on a piece of scrap paper with a pencil, forgot to add "or better". Stated applying everywhere for a while and have gotten may interviews/offers; considering the economy.
One place called me and offered me the exact pay rate, environment, location, I requested from the universe. I'd already forgotten about the list, it fell off the shelf shortly before they called. The job fell through because of budgeting issues last month. But, last week my parking pass fell off my rear-view mirror for no reason and I thought, "Oh, I guess I'm about to get a new job." Yesterday, the company called asking if I was still available and sent me for my drug test.
So yes, it is possible and can be very easy; but, if I had at least put in some meditation, raised the energy, it may have been faster and smoother.
Though if you're asking to do a spell that will materialize instantly...its possible as well, as long as the conditions within and around you are ripe.
Though I still suggest that you take the time to cast your circle and ground yourself; its to protect you.
