It means that we are not committed to the action that we conceived of taking because of it not feeling like the right thing to do.   

Whenever we get into such situations where this Half A Mind state appears we should recognize our need for more discipline.   

That discipline is really the exaltation of principle over thought.   By this I mean that our minds have been transformed to only think from the basis of principle.   

And be not conformed to this world: but be you transformed by the renewing of your mind, that you may prove what is that good, and acceptable, and perfect, will of the Lord. Rom 12:2 What is wrong with the world that we should not be conformed to it?         → it is lost and confused    → it is filled with sickness and disease    → it is filled with violence    → it is filled with greed    → it is filled with hate    → it is filled with death    → it is hopeless    → it is apart from the Lord Conformity is good when it is to the Word and the Holy Spirit.     Otherwise it is evil.      In order for the New Spirit being to manifest in our flesh, we must be transformed in mind, emotions and will (our soul).      When we are transformed we receive the wisdom and power of the Lord to do the work of Christ Jesus in our mortal bodies.      What is the good and acceptable and perfect will of our Lord?         → It is that none perish 2Pe 3:9,    → it is that all be healed 1Pe 2:24,    → it is that all prosper 3Jn 1:2.      How is the Lord`s will proved?         → By the manifestation of evidence.      What evidence?         → salvation, healing and prosperity.      Hence, the only thing holding us back from experiencing the best that the Lord has for us is our minds.      Let the Mind Of Christ be in you.     - Phi 2:5

Let this mind be in you, which was also in Christ Jesus: Phi 2:5 Jesus wants us to be like Him.     After all, He created us in His image Gen 1:26.      He chided His disciples when they did not measure up to their potential.     `Oh you of litte faith, why are you so fearful` Mar 4:40.      Jesus made it possible for us to be accepted by His Holy Spirit through His blood sacrifice Eph 1:6.      Once cleansed He made it possible for us to receive His Holy Spirit Luk 24:49.      The Holy Spirit of Christ is who raised Christ Jesus from the dead Rom 8:11.      He told us that greater deeds would we do as a result of receiving that gift Joh 14:12.      But, in order for us to realize our potential we must `realize our potential` 1Jn 3:2.      As we think in our hearts so are we Pro 23:7.      For me or you to reach our potential in Christ we must believe what He said about us to the extent that we allow it to transform our thoughts, words and deeds Rom 12:2.      The Mind Of Christ is achieved by knowingly and willingly being transformed by the Word and Holy Spirit Phi 2:5.      We must desire to have the Mind Of Christ and we must feed on what He fed on to arrive at the same place He did Mat 5:6.      Jesus said the Kingdom Of Heaven is at hand when He walked the earth Mat 4:17.      In the Word and Holy Spirit we can manifest heaven on earth Mat 12:28.      It is His will but is it yours?     Eph 3:20

Remember, In Christ Jesus we are Spirit Soul And Body with the proper prioritization being:
    1 - Spirit
    2 - Soul
    3 - Body
