“No pain, no gain” may be a fallacy when it comes to working out, but research shows it’s good advice when seeking happiness. According to a study in the Journal of Happiness Studies, working hard to master a new skill, though it causes significant momentary stress, leads to greater long-term contentment. Setbacks and frustration often cause many of us to give up on our goals. But, when it’s for something we care about, pushing ourselves to overcome obstacles helps us achieve more satisfaction in life. Even if your dream feels impossible, go for it anyway.
