I will report a complete lattice calculation of the quark and glue components of the proton momentum and angular momenta. Preliminary results on the quark spin contribution from the anomalous Ward identity will also be reported. Hadron mass can be decomposed in terms of the quark kinetic energy, quark condensate, glue component and the trace anomaly. Results of such a division for the pseudoscalar and vector mesons from light to charm quarks will be presented.
