When things don't go according to plan often the option that comes to mind is giving up.
This is not necessarily a bad thing, but when making this decision, you have to look at the real reason for this question popping up into your head.
Are you thinking of giving up because things are just not moving as quickly or as you hoped? Or are you giving up because you just don't have passion for what you are doing anymore?
The most important factor that plays a crucial point in this questioning, is your passion and desire. If there is absolutely no desire involved then looking to move onto something new can be something to look into to.
On the other hand, if part of you really wishes things would be different and work out then please don't give up.
Sometimes life likes to take us out of the situation and bring us back in, so we can learn from what didn't work before and make those changes that we feel more connected to.
