Hi Nessaj - welcome to SW....I restarted SW in Jan and have just rejoined these forums to try and find some extra support and motivation!
I think the mini goals idea is great. I've lost 1st 9 pounds so far and found little goals really helpful - especially when it is to put you into a lower stone bracket - nothing feels nicer than that!!!
I think the other thing to remember is that we are all human, and we can go a little off track at times, but remembering your goals can keep you focused.
My SW consultant said something yesterday that really inspired me - if you have a bunch of 7 beautiful flowers and one died would you throw away the whole bunch, or just get rid of the dead one and continue to enjoy and admire the good 6? This has really helped me to see that ideally I will food optimise 7 days a week, but if something goes wrong on one day I need to stick at it!!!
