Several other income streams that should not be overlooked:

Pension. Company or government

Government money. Social security, disability, guaranteed income (should that come to pass)

Return on investment. 401k, stock market, real estate

Inheritance, trust fund

Loan, from bank, mortgage

Investor. VC, Crowdfunding

Sale of large asset. House, company

Grant, gift, award

Neglecting any of these, or failing to note when they’ll kick in, will hurt your financial planning.
