You can keep proper Niyyah to convert even Halal actions into Ibadah with reward. As I mentioned in the other thread, one can sleep with the intention of getting fresh to be more energetic for Salah. Eating to get more energy for Ibadah. Exercising to be more strong for participating in Jihad or protection of family. Earning money to spend for the family, spending for family is Sadaqa itself. Also earning money to spend for Masjid, sadaqa etc.
