Putting myself into a situation where I have no choice would mean being constantly in grave danger (financial, social, or relationship). If I fail once, it may have a catastrophic impact on my life. The worst part is that I may fail due to external factors that I have little control over (e.g., getting a huge loan to force myself to work, while experiencing a serious injury that prevents me from working for months). Anything other than looming doom wouldn't work on me.
