Take a nice vacation somewhere.
.....
I don't like that idea at all. If you have to go some place special to take photos, you are not really into photography.
Here is what you can do.....
Go to the library and pick up some large format coffee table books and look at the photos and find a style or a photographer you like. Maybe you like one of the old masters list Westin or some out more recent. Don't matter pick one or two or three.
Next, blatantly attempt to "rip off" their style. Don't worry this is how artists were trained for 3,000 years. First they copy a master and only later they develop their own style.
So like I said find a few styles or people you like and go out one day and shoot 20 to 40 exposures in that style. Run then through your "process" and keep the best 2 or 4 shots. Be VERY selective and only keep the best work. Compare there shots to the books and then try again.
You can find books of landscapes or portraits or even of food photography or animals. Pick a few books you like and don't worry about the ethics of emulating someone else, it has a strong tradition with art students.
That is the key. think of your self's an "art student". To many beginning photographers think about equipment and technical stuff. No study art.
One fun progect is to get a book of Rembrandt painting and try to shoot portraits that use light like Rembrandt did. Copy it exactly. Lok at the angles and the colors and the 'lighting ratio" that is the number of f-stops (or EV steps) different between light and shadows.
