You're defending it because you've already spent five years on it

Sometimes continuing really does make sense. Difficult stages exist. Long timelines exist. Some work takes time to produce visible results. Not every disappointment means you should abandon everything. Then explain what will change. Why will the next attempt be different? What have you learned? Which conditions are new? What result will let you distinguish patience from repeating the same shit? If the only new argument is “now I've invested even more,” the situation hasn't improved. Leaving has just become psychologically more expensive.
