The future can be classified into four views:
- Indefinite pessimism = You know that the future is doomed but you're not doing anything about it.
- Definite pessimism = Same as the above, except you're prepared for it.
- Definite optimism = You see the future will be good, if you work for it.
- Indefinite optimism =You are not sure how the future will turn out, but you're hopeful anyway.
