Ibaadat and Good actions

Exerting oneself in ibaadat

Q: I have a question about the Sahabi who only did the bare minimum and didn't do too many optional acts. When another Sahabi stayed at his house for 3 days he didn't notice anything special that he was doing. Despite this, Rasulullah (sallallahu alaihi wasallam) said he was a jannati. Other Sahaba always followed the azeemat and took the more difficult path. So, as a general rule, should I take the easy path or the hard path when I have to make a decision?

Doing good deeds with the intention of receiving benefits in Jannah

Q: My question is about intention in doing good deeds. I used to ask Allah for jannah just to get the things that I dont get here. Whenever I had any wish on things thats not permissible for us or luxurious life style that we wont get here I used to think inshallah I will get it in jannah and it also motivates me to do good deeds or pray in order to get jannah. Basically my intention while doing good deeds is to get jannah and these worldly adornments there. Are those deeds accepted or is it a sin for keeping such intention. 

Making multiple intentions for good actions

Q: I understand that it is shirk to intend to do worship for the sake of Allah as well as someone else (that the intention should only be for Allah). Is it shirk to have both the intention to achieve something as well as to please Allah when you're doing tasks that normally are not worship?

Say for example, you are cooking, both to feed your family but also because you hope Allah will be pleased with you and reward you for feeding your family. Or, giving your mother a foot massage both to please your mother and to please Allah. Is this shirk? If not, how does it differ?
