  The bootstrap is a technique recently developed to get energy eigenvalues of
bound states and correlation functions. There are three crucial steps -
recursive equations, positivity constraints, search space. We calculate
recursive equations of many representative quantum mechanics systems, such as
polynomial potential, exponential potential, Yukawa potential and
electromagnetic potential. Two kinds of bootstrap matrices, which are about the
coordinate and coupling of the coordinate with the momentum, and their ability
of constraining equations are displayed. Nextly, we analyze possible questions
in numerical search, including the importance of constraints and step length,
eigen-energy level and the degeneracy of energy. Finally, we try to explain why
the bootstrap work well by analyzing positivity constraints of creation
operator and annihilation operator in harmonic oscillator. This article
summarizes most knowledge of bootstrapping quantum mechanics (QM), and displays
specific bootstrap equations and bootstrap matrices of different QM systems.
