Breaking it down to rebuild it a better way

One of my issues is that i'm pretty much on my own in the parenting, the  house keeping, the  providing sustenance and in the planning for a healthier lifestyle. Having a partner who is a brilliant provider but who has hardly any spare time in the week can be pretty tough. I need to be understanding that he needs his down time but it can be really hard when we all get so tired and frustrated with the life that we are currently living. It is my hope that i can influence him and our adorable children by changing as much as i can. As it stands we live an ordinary, average life. We watch tv, they play video games (very limited), i plan meals and shop at grocery shops and buy what we can afford, we buy takeaway, we don't have a very active lifestyle and i'm not proud of how i keep my house at this stage. We are consumer driven and are influenced by advertising and society.
That's just a touch on what i believe are borderline negatives and some definite negatives. I'm 30 and i am starting to let myself get into the frame of mind that 'it's too late', i've lived this way for 30 years of my life and i am wondering how i am meant to make these changes when this current way of living is so ingrained in me. However the thing that saves me from letting this become an all consuming thought process is the fact that my children are 6 going on 7 and 3 going on 4. They still have a whole long life ahead of them and this time in their life is so very important in giving them the tools they can use to live a happy, healthy and fulfilling lifetime. So for me at this stage i need to break it all down so that i can rebuild it all in a much better and healthy way.

The following are the things that i need to alter, i know it will require research, time and effort but here we go down the rabbit hole....

1.My way of thinking.
*Taking responsibility for my roles
*Not allowing negativity to cloud everything
*Taking time to enjoy life

2.The way we eat.
*Implimenting the Paelo eating plan to see if it works
*Cut down or out Takeaway
*Encourage the children to cook and bake

3.The way i run our home.
*Get motivated
*Take pride in where we live
*Create a home that i love

4.My parenting
*Being an available parent
*Better time management and routine

5.The way i look after myself
*Excersise
*Healthy self-indulgence
*Yoga, yoga, yoga!
*Meditation
*Always listen to music as it nourishes my soul.

I feel like i'm slowly getting my mojo back, although sometimes is feel like i'm in a never ending cyclical battle of will, determination and inspiration that is consistently opposed by negativity, tiredness and practicality. I do think I will get there, if not now then at some stage. This is what i really want and the lifestyle that i desire to be living. I want to feel alive and i need to know that i am using this life that i have been born into and blessed with in a way that i will feel content with.
