Couple weeks ago, I've decided to take the DELE B2 exam. I thought it was an stupendous idea because that would improve my Spanish level dramatically. But there were two problems. On one hand that made me stressed and I felt like losing the joy of language learning. On the other hand I was literally sacrificing my whole savings so the stakes are high, what if I failed the exam and lost my money as well. So I forget about that idea and continued learning Spanish for the joy of learning not for the exam.
